Unmanned Aircraft Flying the Pacific Non-Stop In The 21st Century: Why It’s More Difficult Now Than Lindbergh’s Flight In 1927

Flying non-stop across the Atlantic for Charles Lindbergh was difficult on the man, the machine and on technology. Once engine endurance improved, the only thing left to prove that cargo and passengers could move safely across the Atlantic – non-stop – with only human endurance as the last barrier to...

Progress on the HY4 Hydrogen-Fuel-Cell-Driven Passenger Aircraft

The increasing electrification of aircraft systems from actuators to “green taxi” and main electric propulsion typifies a wide field for interdisciplinary research. The German Aerospace Center in Stuttgart, mainly represented by the “energy systems integration” group at the Institute of Engineering Thermodynamics intensified its activities since 2007 in this interesting...

Urban Air Mobility – The dominance of land based commuting is coming to an end

New materials and technologies are enabling a push toward cleaner, quieter, urban air transport solutions and greater e-mobility. However, challenges from regulatory and environmental issues surrounding urban air operations and historical aviation experience, require us to consider the ‘bigger picture’ in order to deliver viable air transport solutions. Faradair® is...

Empowering Autonomy with the Next Generation of Lightweight Solar

Alta Devices will present its latest Gen 4 high-efficiency lightweight solar technology developed especially for things that fly. The new platform offers even lower weight, reduced thickness and supports higher-efficiency multijunction solar cell designs.
Dr. Aarohi Vijh

Sustainable Skies Keynote Lecture – Electric Air Vehicle Performance Prospects: Comparing eVTOL versus USTOL

There is much current hype about eVTOLs. But how realistic is their potential for development as PAVs when compared to USTOL aircraft? This presentation provides the results of analysis that predicts the best possible performance (range and number of passengers versus power and energy required) for both eVTOL and USTOL...

Where the Rubber Meets the Road: Quieter Runway Strategies

Tire-pavement noise can be the prevailing noise source when aircraft are ground borne in communities. This presentation will discuss quieter pavement and barrier technology and the impact of reducing aircraft noise in communities during ground borne activities.
Dana Lodico

High Torque, Low RPM Motors – Key Enablers of Quiet Flight

Motor expert David Calley will discuss the tremendous benefit of high-torque low-RPM motors for sustainable quiet flight.
David Calley

The Electric VTOL Revolution

This presentation will discuss the promise and progress of electric vertical take-off and landing (eVTOL) aircraft​. More than 65 eVTOL concepts are being studied around the world, with several advanced prototypes already conducting impressive passenger-carrying flights. Companies like Uber, Airbus, Bell, Joby and Kitty Hawk are competing to develop the...

Aero Theme Dinner: Aerodynamics of the Electric Aircraft and its Rotors

This presentation on practical and classical aerodynamics covers a range of little-known but fundamental data and methods key to the aerodynamic design of airfoils, wings, and rotors. Both vortex-integration and blade-element methods are reviewed, validated by data, and applied to evaluate aircraft and rotor aero loads. The methods are then...

Principles of High-efficiency Electric Flight

The ubiquitous permanent-magnet brushless motor-generator and bi-directional power conditioning are reviewed and optimized as a system, including the battery, with the aid of simple circuit modeling validated by test data. A notional low-speed “regen” electric aircraft is introduced, applying the proposed method of electrical-power optimization and using its rotors as...

Future Helipads, Vertiports and Pocket Airparks for Urban Air Mobility

This presentation addresses the design and planning aspects of future “air piers” for Urban Air Mobility (UAM). First, the presentation reviews critical issues faced by airport and heliport planners and designers in the last 50 years. It pays special attention to previous UAM concepts developed in the USA, such as...
